Abstract In craniotomies, the surgical manipulation of instruments inherently involves applying mechanical forces to brain tissues, potentially causing brain damage. Currently, there is no direct method to quantitatively monitor craniocerebral injuries. Here we report a soft neural interface bioelectronic system (SNIBS) for real-time monitoring of craniocerebral injury throughout neurosurgery.

Abstract Conformal fabrication of stretchable conductive film on micro-structured surfaces is important for flexible electronics. Existing methods based on material design and structural engineering suffer from limitations in stretchability, conductivity, and geometrical compatibility. Here, we propose a universal strategy for fabricating high-performance stretchable conductive film on complex micro-structured surfaces.

Abstract Conventional implantable electronic sensors for continuous monitoring of internal tissue strains are yet to match the biomechanics of tissues while maintaining biodegradability, biocompatibility and wireless monitoring capability. Here we present a two-dimensional phononic crystal composed of periodic air columns in soft hydrogel, which was named ultrasonic metagel, and we demonstrate its use as implantable sensor for continuous and wireless monitoring of internal tissue strains.
